Great
Great clips love them.

Great for Shibari Rigging
These have become my favorite for doing suspension work. Easy to set with one hand. Larger for laying in more lines. The color is beautiful.

Works Well for My Use Cases
To be clear, I do NOT use these for holding my bodyweight for any activity. Not saying they can't be, just that I don't. I do, however, use them for attaching things to my harness, such as a reasonably heavy camera combination (5kg/11lbs) or a water bottle. They've been on several "adventure course" type of activists and ziplining and they work great. No accidentally opening the carabiner given how they auto lock, and they work fine with either hand and even while wearing gloves. I haven't noticed the weight being an issue, but again I'm not a climber where that may be more important. They're princely overkill for me, but the price fit and the features/profile matched what I wanted.

A high strength rating for this style carabiner. The spring loaded to lock design is desirable.
I wanted carabiners with a 30 kN rating and this item was competitively priced. Their appearance exudes quality. With the spring loaded to lock position design, forgetting to lock the item is not an issue.

Great to use on the anchors of your truck bed!
These are good quality and look nice. I use them in my truck bed to attach to the anchors for easier use when securing loads.

easy and large
delivery came super quick. The construction on these are solid. The locking mechanism is easy. They’re larger than expected, but I need a large carabiner for this project. I didn’t like how they individually wrapped, but I can live with that thanks.

Will order more soon
Very nice. Well built. I use them as clips on backpacks and on both headrests in my vehicles to hold keys and other things. Very tough built

Item arrived well-packaged. The karabiner itself seems well-made and well machined. Gate is easy to operate, with a twist and push mechanism. Haven’t fall-tested it yet, but it looks and feels reliable!

Good carabiners, but not for ppe! It has no three way opening mechanism.
